In David S. Goyer's newest film, "The Unborn," a young girl is terrorized by an ancient spirit, an entity that is trying to get back into our plane of existence and be born again.

In an article we just published we took a look with Goyer at how that spirit, taken from the Hebraic legend of the dybbuk, influenced his film's nightmare logic and dream imagery, how he purposively left it unexplained to be more frightening.

Well that -- or to save for the sequel.

"The spirit in my film is based in kind of Old Testament mythology. But the whole idea with the entity is that it dates back even further than Judeo-Christian religions. The basis is in mythology and I kind of crafted and added on to it," Goyer explained. "We actually don't know where it really came from. The first thing it inhabits is a young child but it kind of hops bodies throughout the movie. If we're fortunate enough to do a sequel I would delve back even further because we don't say were it really originated from.

"You never go into a movie saying, 'Hey, let's set it up for a sequel,'" Goyer added. "But there were some questions that I found really compelling and that's one of them."

Co-starring Gary Oldman and Carla Gugino, "Unborn" is an "old-school horror film," Goyer said, citing "The Exorcist," "Rosemary's Baby," and more recently, "The Exorcism of Emily Rose" as examples of similar movies.
